Interesting -- thanks! I changed all those ornaments.
And what about the aforementioned tables, then? Wrap all those in a "text-align: center" div, too, basically? Will that keep the width of the table to a minimum (assuming it's not so "full" with stuff that it stretches to the width of the margins, of course)? I know I can try this out myself and see, but my inability to see what happens on other devices that I can't do, of course.
